朱砂叶螨精子染色质高度浓缩，无核包被、鞭毛和顶体结构，精子内部无线粒体和核糖体。精子双层膜厚度为０．０１５～０．０２５μｍ，精细胞管状膜的高度和宽度分别是０．２５～１．３３μｍ和０．０２５～０．０３３μｍ，精子和核直径分别为１．３～１．５μｍ和０．６～０．７μｍ。精子形成时，首先精子内核物质分散、有包被，无管状膜内陷；然后管状膜内陷．放射状；接着管状膜内陷不断扩展成为小囊泡状，核物质集中在中央，校包被消失；最后管状膜囊泡状内陷排列从无序走向有序，形成成熟的精子。
Trichosanthes spider mite chromatin is highly concentrated, non-nuclear coating, flagellum and acrosome structure, sperm inner mitochondria and no body. Sperm bilayer membrane thickness 0.015 ~ 0.025μm, sperm cell tubular membrane height and width were 0.25 ~ 1.33μm and 0.025 ~ 0.033μm, sperm and nuclear diameter were 1.3 ~ 1.5 μm and 0.6~0.7 μm. Sperm formation, the first sperm core material dispersed, there is coating, no tubular film retraction; and tubular film invagination. Radial; then the tubular membrane retraction expanded into small vesicles, the concentration of nuclear matter in the center, the school bag is disappeared; the last tubular membrane vesicular invagination to orderly disorder, the formation of mature sperm.
